Odontogenic tumors constitute a group of heterogeneous lesions of benign and malignant neoplasms with variable aggressiveness. Ameloblastomas are a group of benign but locally invasive neoplasms that occur in the jaws and are derived from epithelial elements of the tooth-forming apparatus. We previously described orosomucoid-1 protein expression in odontogenic myxomas. However, whether orosomuc...

Benign neoplasms of the colon, rectum, anus and anal canal are true neoplasia colon mucosa associated with a high risk colorectal cancer (CC). The literature review analyzes epidemiology, factors, modern methods diagnosis treatment, describes priority minimally invasive interventions for benign tumors.

Neoplasms in sinonasal cavity are dominated by epithelial type. Sinonasal osteomas common, benign, slow-growing, often asymptomatic neoplasms occurring mainly the frontal and ethmoid sinuses. Peripheral nevre sheath tumors soft tissue rarely encountered region. Schwannoma is a benign peripheral tumor. Here, we presented co-occurence of osteoma schwannoma. So far, infiltrated schwannoma region n...

The aim of the study was to assess the intensity and distribution of galectin-3 expression in benign and malignant thyroid neoplasms by immunohistochemical method. Immunohistochemical expression of galectin-3 was analyzed in surgical thyroid specimens from 82 patients with histopathologic diagnosis of follicular adenoma (n = 32), Hürthle cell adenoma (n = 10) and papillary carcinoma (n = 40). R...

Mixed testicular tumors are of great interest both clinically and pathologically. Being in most cases benign neoplasms, they sometimes give rise to metastases, some subjected malignant transformation, so that their timely recognition is particular value. In the pathological anatomical sense these neoplasms relation microscopic structure, often extremely complex histogenesis.

The National Toxicology Program (NTP) classification system for rat and mouse ovarian tumors is presented. The classification system is based on previous classification systems and on a review of all the primary ovarian tumors from the archives of the National Cancer Institute (NCI) and NTP Carcinogenesis Testing Programs. The relative frequency and principal diagnostic features of 204 ovarian ...

Lipoma, a benign tumor of adipose tissue is one of the most common benign neoplasms of the body. However, lipomas in the oral and maxillofacial region are rarely encountered. It accounts for 1 to 4% of benign neoplasms of mouth affecting predominantly the buccal mucosa, floor of mouth and tongue. We report a case of intraoral lipoma in buccal vestibule in which surgical excision was done under ...

A comprehensive cytologic study of a large series papillary lesions the breast suggests combination new features to distinguish benign neoplasms from malignant ones.
